If there is no refrigerant piping embedded in
the wall, do the following:
1. Based on the position of the wall hole relative
to the mounting plate, choose the side from
which the piping will exit the unit.
2. If the wall hole is behind the unit, keep the
knock-out panel in place. If the wall hole is to
the side of the indoor unit, remove the plastic
knock-out panel from that side of the unit.
(See Fig. 4.6). This will create a slot through
which your piping can exit the unit. Use
needle nose pliers if the plastic panel is too
difficult to remove by hand.
3. Use scissors to cut down the length of the
insulating sleeve to reveal about 15cm (6in)
of the refrigerant piping. This serves two
purposes:
To facilitate the Refrigerant Piping
Connection process
To facilitate Gas Leak Check s and enable
you to check for dents
4. Connect the indoor unit' s refrigerant piping
to the connective piping that will join the
indoor and outdoor units. Refer to the
Refrigerant Piping Connection section
of this manual for detailed instructions.
5. Based on the position of the wall hole
relative to the mounting plate, determine the
necessary angle of your piping.
6. Grip the refrigerant piping at the base of the
bend.
7. Slowly, with even pressure, bend the piping
towards the hole. Do not dent or damage the
piping during the process.
This unit must be installed by a professional according RD 795/2010, RD 1027/2007 and RD 238/213

Step 5: Connect drain hose
By default, the drain hose is attached to the left-
hand side of unit (when you're facing the back
of the unit). However, it can also be attached to
the right-hand side.
1. To ensure proper drainage, attach the drain
hose on the same side that your refrigerant
piping exits the unit.
2. Attach drain hose extension (purchased
separately) to the end of drain hose.
3. Wrap the connection point firmly with Teflon
tape to ensure a good seal and to prevent
leaks.
4. For the portion of the drain hose that will
remain indoors, wrap it with foam pipe
insulation to prevent condensation.
5. Remove the air filter and pour a small amount
of water into the drain pan to make sure that
water flows from the unit smoothly.
NOTE ON DRAIN HOSE
PLACEMENT
Make sure to arrange the drain hose
according to
Fig. 4.7
DO NOT kink the drain hose.
DO NOT create a water trap.
DO NOT put the end of drain hose in
water or a container that will collect
water.
